How much boost to set for K24/18G with Greddy Profec B Spec 2 & Turbo Timer ?
#16
These turbos are great! I just took my car out this weekend for a test drive of the Proto air intake system I recently installed and the 24/18's were so responsive and pulled so strong up top. All this talk of K24 lag....I certainly don't have it and I think the car pulls harder with the intake.
And - it still needs the updated file for the intake - it is running a little rich at WOT with the old file, so there is more to come with the proper tune/file. The 1/4 mile will tell the story - it will be interesting to see if the time/trap improves due to the addition of the Proto air intake, Y-pipe, etc....

Do you feel the 75mm TB and the IPD plenum are worth getting and do they contribute to any more horsepower?

Vince,
I think they are definitely worth getting if you are going the full 700 route with Y-pipe, as they will increase the HP and torque, but I am not sure otherwise. I did them in conjunction with so many other upgrades that it is impossible to tell what they contribute to the mix. I know that Todd recommends them in his 700 package and says they do improve the mid and top end. He did say that without an enlarged Y-pipe to feed the larger TB, it can't do much because the additional volume of air it can flow is not being supplied to it with the smaller OEM Y-pipe. That said, I did have it in conjunction with the OEM Y-Pipe last season and my car ran pretty strong. I would do it again.

Thanks for all the info. At this point I am just planning on getting to 600 Flywheel Horsepower. Going to set the Greddy Profec to 1.1 and strap it on the dyno and see what we get. I am trying to source the upgraded wastegate springs currently. What PSI spring do you have in your K24 18G wastegates?

but with the greddy you can boost it up( assuming you have better gas).

From what I know ... 1.1 bars on pump max..... I would even in your case drop it to 1 bar.... I would run 1.2 bars on 100 octane and 1.3 bars 1.3 or higher.... if u run C16 u can do 1.5 bars .... and of course take a peak at your afrs...

Well just to muddle it up some more. I have been working with Todd at Protomotive, on the k24/18g kit, and for 91 octane he suggests 1 bar and for 93 and above 1.2 bar. This is what I will be setting mine at, once it gets here and installed.

Thanks everyone for providing some helpful insight to my question.
I just ordered some custom wastegates for my K24 18G setup from Speed Gallery today. I think Sam said they are 1.2 bar. Should have them tomorrow. I think I will run 1.0 bar first at 91 octane and look at the A/F data first before deciding to boost it up.
On a side note if I was thinking of upgrading to the IPD plenum. Should I get the 75mm with a new throttle body, or just get the 70mm?
